LinuxCNC 2.10 build

Category: Installing LinuxCNC

Thank you for your responses.

I tried the following:
DEB_BUILD_OPTIONS=nodocs dpkg-buildpackage -uc -B
DEB_BUILD_OPTIONS=nodocs dpkg-buildpackage -uc -b
and a few others but always get exactly the same result.

looking at man dpkg-buildpackage I see
-b equivalent to --build=binary or --build=any.all
-B equivalent to --build=any

nodocs isn't an option for DEB_BUILD_OPTIONS by default but it does note "that other options honored by debian/rules might be defined by distribution specific policies." So now I'm off chasing that down.

I also noted that under man dpkg-buildflags(1) there is some interesting info on fortify. I'll chase that later if that problem remains.

Could (I suspect) be distro related so I expect some settings/options will need to dialed in.

G7x and profile in subroutine with parameters

Category: G&M Codes

M2 should always be outside a subroutine, so place M2 after each endsub, and your construct should work.
As you can only use 2 variables, and there is no option to enter a global variable in MDI, it will be difficult to bring the values to your code.
The contur o100sub is in the macro file. If you keep it like that, you need to modify in the macrofile anyway. how about use the default values #3 #4 #5 as this might not change often, only submit #1 and #2 as variable.

Installation 2.9.4 Debian Bookworm Preempt-RT ISO // Probleme

Category: Deutsch

Problem 1
This is an annoying bug in Debian outside of our control which we tried to work around.
Try
sudo apt update  
sudo dpkg -P raspi-firmware

Problem 2
Try my installation notes (English I am sorry)

Installation 2.9.4 Debian Bookworm Preempt-RT ISO // Probleme

Category: Deutsch

Hallo Zusammen,

ich installiere zur Zeit einen Rechner mit der aktuellen 2.9.4 Iso
und habe ein paar Probleme.
Der Rechner hat ein Fujitsu D3220 Board mit i3 / 3,4Ghz , 16 Gb Ram und  Parallelport

1. Problem
Die Installation läuft erst einmal fehlerfrei, allerdings kommt beim Update
folgender Fehler:
Paketlisten werden gelesen… Fertig
Abhängigkeitsbaum wird aufgebaut… Fertig
Statusinformationen werden eingelesen… Fertig
Paketaktualisierung (Upgrade) wird berechnet… Fertig
0 aktualisiert, 0 neu installiert, 0 zu entfernen und 0 nicht aktualisiert.

Nach dieser Operation werden 0 B Plattenplatz zusätzlich benutzt.

Keine Ahnung was das zu bedeuten hat
und ob das vllt. die Ursache für die anderen Fehler ist

2.Problem
Der Latency Test zeigt , wie ich meine, sehr gute Werte
(Ich habe zur Sicherheit 30.000 im Stepconfig eingestellt)
 
aber wenn ich das Programm starte gibt es gelegentlich Ausreißer und eine Warnmeldung das der Wert
über 100.000 liegt.
Im BIOS habe ich ein paar Einstellungen probiert, was aber nicht geholfen hat

3.Problem
Wenn ich die Maschine ( CNC-STEP Zero3 ) mit Stepconfig konfiguriere
so bekomme ich sie mit gmocappy zum laufen.
Wenn ich allerdings, ohne weitere Änderungen auf die schönere QTdragon Oberfläche umschalte weigert sie sich.
Die LED der Ladungspumpe geht nicht an, diese scheint nicht aktiv zu sein

4.Problem
ich wollte noch DXF2Gcode nacht dieser Anleitung 
github.com/ltspicer/dxf2gcode.linux.installer
installieren
Da kommen aber auch nur, für mich, kryptische Fehlermeldungen

ok, z motor hooked up and powered.

im basically lost at this point.

anyone want to walk me through or point me to nice simple sequential "do this then this" instructions?

as of right now i did the ethercat install, and nothing much else. if i type ethercat slaves in the terminal it shows me nothing.

here is my drive manual

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Hello,
Does anybody know how data is formatted for NVMPG to display XYZ data, etc.?
I wanted to use this mpg in another project, but I cannot make it work from source files for stm32 and linuxCNC.
If anybody has a spreadsheet of these signals or a logic analyzer to see what is going to the mpg, I would be grateful, and I could make a tutorial about using it for other stuff as a cheaper alternative to other mpg.
All I know for sure at the moment is the baudrate and button codes, but it was an easy part of it...
Thank you in advance

As Tommy said, balls screws are a poor choice as you can't get the speed out of them and they whip.
Either belts or rack and pinion (with 3:1 to 5:1 reduction)
nodocs has changed. refer the docs :)

; Set default values

Safety Light

Category: Plasmac

The attached is old hal code that Todd helped me with  which uses, red, orange and green lights. The green light flashed (via siggen) when a program was paused. red was from the estop

The Run/Step/Pause/Resume part is described in hal examples on the forum but it won't work with QTplasmac which has its own pins that achieve a similar result.

Her is and example of it running. I did eventually wire this into some stack lights like you show,

G7x and profile in subroutine with parameters

Category: G&M Codes

Hi,

I'm trying to write a macro for touchy that provides the option to specify the x/z coordinates of the G7x profile on the touchy user interface. 

My initial thought was subroutine nesting but I just found out that I cannot nest subroutines. So this does not work:


O<g7x_macro> sub
O100 SUB
...
O100 ENDSUB

G71.1 Q100 ....

O<g7x_macro> endsub


What works (a bit) is to put the profile subroutine after the main macro (before does not work).

O<g7x_macro> sub

G71.1 Q100 ....

O<g7x_macro> endsub

O100 SUB
...
O100 ENDSUB

But now I struggle with getting parameters to the subroutine. Does anybody have an idea here?

These plots don't look correct. Try using halscope. This plot shows on piercing the arc voltage goes right off the page almost instantly then it falls below the cutting voltage before stablising around the cut voltage.
The blue line shows when the THC was enabled and you can see that the voltage has already stabilised before it comes on.

Mesa makes a board that does pwm to analogue.

Yeah I went that whole route when I was using machine kit and a beagle bone black.
It's a shame that the BBB hasn't had a upgraded CPU with the PRU and more memory. Was a great little platform, actually still is but a little underpowered.

Will agree that there are some great tools out there. I still have a copy of the DOS version of EasyTrax I was given by a very surly PCB maker, top bloke but didn't suffer fools.

How would I check this? Toolpath looks complete when zooming in and the "show toolpath data" looked similar for all the circles. I also tried a different part and it came out fine. The selected contours are all closed chain, so not sure what is missing with this part.
